Turnout support system applicable to straddle type monorail

Abstract

The invention discloses a turnout support system applicable to a straddle type monorail and belongs to related technical fields of straddle monorails. A continuous rigid frame in a longitudinal direction and a plurality of support units which are arranged below the continuous rigid frame at intervals in the longitudinal direction are arranged, the continuous rigid frame is fixedly connected with apier cover beam at the top of the support units, then a rigid system with synergetic stress is formed, and a turnout system can be stably supported effectively on premise that the setup height of a support system is reduced. The turnout support system applicable to the straddle type monorail, which is disclosed by the invention, is simple in structure, simple and convenient to set, small in construction difficulty and high in construction efficiency, a straddle type monorail turnout system can be effectively and stably supported, the height of the cover beam and the overall height of the turnover system are reduced, the construction cost is reduced, great flexibility is provided for design of stations and rails of the straddle type monorail, good application prospects and popularization and application values can be made, and popularization and application of the straddle type monorail can be effectively promoted.

Description

technical field [0001] The invention belongs to the related technical field of a straddle monorail, and in particular relates to a turnout support system suitable for a straddle monorail. Background technique [0002] Straddle-type monorail traffic is a kind of urban rail transit. It often has the advantages of low noise, strong adaptability, small footprint, low construction cost, and short construction period. The construction period of straddle-type monorail traffic is often not as good as that of subway construction. Half of the cycle, the construction cost is only about one-third of the subway, but it is a medium-capacity rail transit system, which can greatly improve the city's traffic problems. Therefore, the straddle-type monorail has been applied to a certain extent in some cities in our country, and has begun to be planned and constructed in more and more cities. [0003] Due to the similarity of the operating forms, the existing light rail transit is often compar...

Problems solved by technology

Although the above structure can be applied to existing rail transit forms such as ordinary light rail transit to a certain extent, it cannot be fully applied to straddle monorail traffic

Specifically, if the interval turnout beam of a straddle monorail adopts a continuous beam structure, the structural schematic diagram of its cross section is usually as follows image 3 As shown in ; due to the high height of the mechanical turnout device of the straddle-type monorail, the height difference between the top surface of the turnout and the top surface of the continuous beam is relatively large. The beam height must be large to meet the force requirements; moreover, under normal circumstances, in order to ensure that the operation of the straddle monorail does not affect the ground traffic, the support system of the interval turnout beam is often set in the green belt in the road, but the green belt in the road It is often narrow, so it is often necessary to adopt a single-column pier with a large cantilever structure, and the height of the cover beam at the top of the pier column often needs to be set relatively high, which leads to a large overall structural combination height of the support system and poor urban landscape

In addition, considering the need for road clearance, the increase of the beam height will usually increase the elevation of the rail surface, which makes it difficult to connect the track of the straddle monorail to the station, and the setting height of the station is also affected accordingly, resulting in the straddle monorail. The design difficulty of monorail-related structures increases, and the construction cost increases accordingly

In view of this, the existing continuous beam structure suitable for ordinary light rail interval turnout beams cannot be fully applied to the design of interval turnout beams for straddle monorail, and there are large application limitations
